Genus Axonopus Family Poaceae

Description: Stoloniferous or tufted perennials.

Leaves with ligule narrow, membranous; blade folded in bud.

Inflorescence digitate or subdigitate; spikes 1–many, slender, sessile; spikelets closely appressed.

Spikelets solitary, dorsally compressed, alternate in 2 rows on 1 side of the triquetrous rachis, falling entire from their rudimentary pedicels, the back of the fertile lemma abaxial; florets 2, the lower sterile, the upper bisexual. Glume 1, equalling the spikelet, oblong-elliptic, 2–4-nerved, lower glume absent. Lower lemma similar to the upper glume, glabrous or sparsely silky near the margins, the midnerve often suppressed, without a palea; upper lemma hardened, obtuse, glabrous, nerveless, with inrolled margins tightly embracing the palea. Palea equal to its lemma. Lodicules 2, minute, broad-cuneate. Stamens 3.

Distribution and occurrence: World: c. 35 species, America. Australia: 2 species (naturalized), Qld, N.S.W., W.A.
